I'm in he-l-l.  Baby hasn't slept more than a 45 min stretch tonight, its almost 5 am.
She
 is about 13 weeks old and used to do maybe one 4 hour stretch and at 
least 2.5 - 3 hour stretches for the rest of the night (about 8 pm - 9 
am)
She no longer will really breast feed as of 2.5 weeks ago.  
Sometimes she would during the night so I have been pumping and giving 
bottles.
The sleep seems to be deteriorating and now I am at my breaking point.  This has happened off and on since she was born, but now it seems to be the norm.
Here's what I've tried over the past few nights:
-unswaddling (she was squirming all over her crib anyway).  Right now she is back in her swaddle.
-formula (heard it is slower to digest than BM)
-increasing oz during the day (no help with sleeping, only increased spit up and I think I over-fed)
-white noise
-swing
-pacifier
-rock n play 
She falls asleep pretty well/easily but will be awake in 30-45 mins screaming her head off.
I
 have been respecting her nap times and we don't do anything pretty much
 until after her morning nap that ends around 11.  Usually we don't even
 go for a walk or anything until after her next nap that ends around 1.
I'm going back to work in 2 weeks and I can't do this.  help.
